Cform Problem – Form doesnt send/Freezes

Hi There

Cform Version 9.3
Wordpress Version 2.7.

This plugin has been working fine up until recently ( not exactly sure when as i just designed and built it on wordpress ) But for some strange reason all the forms on the site wont send.

You can fill out all the details and everything fine – But as soon as you hit Send. The send button dissapears and you just get the hold message – Nothing happens from there.

Ive tried de-activating the plugin then reactivating, Also completly removing the plugin files and re adding them.

Any help would be greatly appreciated.

You can see an example of it here https://www.starjam.org/become-a-volunteer/

Thanks
